Oven Temperature Sensor Probe
This Resistance Temperature Detector (RTD) operates on a predictable ohm-to-temperature coefficient; if the internal platinum film or ceramic substrate degrades, it sends an incorrect resistance signal to the control board. The board interprets this high resistance as a low-temperature state and continues to energize the heating elements indefinitely. Replacing this sensor restores the accuracy of the feedback loop used to regulate thermal equilibrium.

Electronic Oven Control Board
The control board contains mechanical relays that cycle power to the bake and broil elements. Over time, electrical arcing across these contacts can cause 'contact welding,' where the silver-alloy pads physically fuse together in the closed position. Once fused, the board loses the ability to interrupt the circuit, leading to a thermal runaway regardless of the temperature sensor's data.
